The platform driver remove function needs to release the memory resource

Add eventfd which notifies userspace about ep0 events and AIO completion

we need to poll on single file (instead of polling on ep0 and eventfd's

FunctionFS eventfd is not triggered if another eventfd is supplied to
AIO layer (in AIO request). It can be useful, for example, when we want
to handle AIO transations for chosen endpoint in separate thread.

This pull request is based on the last round of SoC updates for v3.19,
Fourth Round of Renesas ARM Based SoC Updates for v3.19, tagged as
renesas-soc3-for-v3.19, merged into your next/soc branch and included in
v3.19-rc1.
- ARM: shmobile: r8a7740: Instantiate GIC from C board code in legacy builds
Set .control_parent for all irqpin instances for sh73a0 SoC when booting
using legacy C.
- ARM: shmobile: r8a7740: Instantiate GIC from C board code in legacy builds
This fixes a long standing problem which has been present since
the sh73a0 SoC started using the INTC External IRQ pin driver.
The patch that introduced the problem is 341eb5465f ("ARM:
shmobile: INTC External IRQ pin driver on sh73a0") which was included
in v3.10.

The arndale-octa board was giving "imprecise external aborts" during
boot-up with MCPM enabled. CCI enablement of the boot cluster was found
to be the cause of these aborts (possibly because the secure f/w was not
allowing it). Hence, disable CCI for the arndale-octa board.

The arm-cci driver completes the probe sequence even if the cci node is
marked as disabled. Add a check in the driver to honour the cci status
in the device tree.
